1992 325i. Bad relay has indicated for this car, resulting in idling problems. Replaced 02 sensor already which improved things, but still need to replace or maybe just clean the idle control valve.

Anyway, I've attained a brand new relay for the fuel delivery system (light green), probably a multi-function relay. A little embarassing, but I can't figure out where it goes! Fuse box schematic only indicates fuse locations, not relays. Even the relays in the fuse box itself! (aside: why is that?). Can anyone tell me where the fuel pump relay is located?? It is part # 61368373700, light green, 5-pin. Searched the internet for days, but no schematic exists online. Maybe someone here has a repair manual with this info? Thanks so much!

Okay, well, my manual says that the fuel pump relay is in the underhood fuse panel box and can be removed using the fuse removal tool that is stored in it. The book makes it sound like it's a regular looking fuse but you say it's a 5 point (squareish?) type thing. I would just pull each one out and see if the new one fits and then try starting your car. Sounds hillbilly but may work. Keep us posted.

I may try looking at them again, but I already pulled each one to compare part #s, and there was no match. This is not one of the little fuses, but indeed a small box-type relay, about an inch and half on each side, square, 5-pin. It could fit in any number of places, but I don't necessarily want to go around swapping out fuses to see what happens quite yet.... I'm wondering though if the exact part #s need not match? Still, fact that there is no schematic for relays in the fuse box itself is troubling. All the fuses there are clearly marked, however....

if you are facing the car from the drivers side. it is the 2nd row, and the 2nd from the rear. it should be pretty much in the middle. i figured out by jumping each terminal and listening for their reaction of each. this may be different beings my car is a 318, but it should be the same. good luck

sry i was off, by one, it is the 3rd one across. you should have a row on the very inside if you are looking in from the side of the vehicle on the drivers side. there is only 3 in this row. so what it should look like from the side is a row of fuses 21-30 that should be on your fuse box lid diagram, a row of 3 relays then another row of 3, the the last row of 3. the fuel pump relay is located in the 3rd row of relays and is the first one counting towards the back of the engine compartment.
Here is a picture of it, even though it isnt that clear. It is the #1 relay postion in the picture. Hope this helps.

I don't have an answer but I am looking for the fuel pump relay as well for my 1992 BMW 325i. My fuse box looks different then the one showing. Did you find the relay in your car if so could u tell me where it is?

OK, I found the fuel pump relay finally. Don't have tools to test relay. Do you know where I could go to have it tested? I checked with the auto store, they couldn't help me. And yes the starter turns, car won't start. My fuses are not clear, how do I check them. As you can tell, I'm not that experience with cars. Sometimes you just have to things for yourself.

I took another relay out that matches the fuel relay, and try it in the fuel slot and car still won't start. So I guess now I need to check the filter and pump. Would this b the next place to start looking?

Help!!

so i went to get the fuel pump relay on my 325 last night, and i rediscovered that the relays have apparently been replaced before i owned the car. whatever connector used to be there is now just the loose wires with female blade connectors on them. in this process, i forgot which wires went to which blade. can anybody look at their fuel pump relay and let me know which wires go to which? the identical relay that it is next to also got disconnected and confused. any help would be appreciated!!
